I have some suggestions to help you get this going. I have both the 8gb and 16gb NTs working just fine.

You say you are copying the “boot.img” to the CM9 rom zip. If you are talking about “cm9.img” that file goes into the sdcard partition.

Experiences:

First partition, make it 1001 mb. (Or 2001, 3001, etc.) I have expanded this to 16001 on a 32gb, and found by trial and error that this seems to be the largest that it will accept.

What I have found is that not all microSD cards are same. Some cards can be used to boot the Nook tablet and some cannot. I also have a Raspberry Pi, and the same is true there. (If it works in the Pi, it works in the Nook). So, if the card doesn’t work, try another. I don’t know what makes the difference, but I have a SanDisk 8 GB, and that doesn’t boot.

When redoing the card between tries, delete all partitions and create a Fat32 partition and then erase it before creating your partitions to use.

Instead of “system1” name the partition “system”. This helps with the Gapps file later on.

Hope this helps.
